SPECIFICATION forming part or LettersPatent No. 629,104, dated .nn s, 1 99. V v f Application filed novemtefsdisev.sen inaeeoeza. N model-l' Be it known thatI, KARL EGGEMANN, a subject of the Emperor of Germany, residing in Kleinlaufenburg, Baden, Germany, have invented certain new and useful Improvements in Apparatus for Examining Umbrella Stuffs and the Like Cloths, (for which I have obtained a patent in Germany, No. 89,261, bear ing date April 8, 1895; in Switzerland, No. 11,145, hearing date November 29, 1895, and

hearing date December 30, 1895,) of which fication.

This invention relates to certain improvement and use of an adjustable glass plate, over which the clothespecially umbrella stuff-to be examined is carried in a stretched state, so that all defects which occur in weaving may be easily recognized and corrected.

The invention consists, further, in the com bination of said plate with a-reflector, which assists the examination by collecting the rays and reflecting them on the plate. V

How I carry my invention into effect is shown on the accompanying drawings, described hereinafter, and'finally pointed out in the claim at the end'of' this specification. 1 In the accompanying'drawings, Figure 1 is a side view of 'the examination apparatus, partly in section. Fig. 2is a front view of the same. Fig. 3 is'a plan. Figs. and 5 are horizontal sections along lines I I II II of Figs. 1 and 2.

Similar numerals'of reference indicate corresponding parts.

The machine consists of two pillars of castiron 1 and 2, which at the top are connected by a bridge 3 and at their bottom by bolts 4. To the upper end of this frame are screwed bearings 5, in which is located a roller 6, from which the cloth is supplied to the device for examination purposes. The roller 6 is provided with a brake, consisting of a disk 7, keyed to one end of the-axle of roller 6, over which is arrangeda brake-band 8, that is fixedat one end to-the frame and at its other end to a lever 9, which is acted upon bya weight 10, as n will be easily understood that by this arrangement the, stud maybe pulled off from the roller 6 more or less rapidly.

The examination device consists of a square frame 10,which is adj ustably located between the pillars 1 and 2. For this purpose it is provided with pivots -11, whichmay turn in corresponding mortises of sliding pieces 12, arranged at each inner side of the frame. By means of racks 13,'fixed to the slides, and pinions 14, fitted to the pillars 12, or vice versa, the framelO may be raised and 'lowered if the cranks 15, situated on the spindles of said pinions, are respectively turned,

and it may also be adjusted in the vertical plane by being turned around its pivots.

The frame 10' has a number of leading rollers, preferably three, 16 17, which form the cross portions and are so arranged that two rollers are at the rear edgeand one at.

the front edge of the machine. Between two rollers 1617 the frame is open, and this opening is covered by a'pla'te 18 of mirror-glass,

which fits into a corresponding recessof the frame 10. This plate serves as-support for the cloth, whichcoming from the supplyinghappen by weaving, so that the same maybe easily corrected by striking-the respective .warp an d weft threads with a suitable instrument-for instance, a blunt knife.

For operating the device the machine must be placed near a window to catch the broad daylight; but in order that, the glass plate may be also suitably enlightened on dark neath the frame 10 a reflector. The reflector consists of. two lengthwise and two crossbars 19, which are joined together in any convenient manner to form a frame. This frame is rotatably mounted in the pillars" 1 and 2 and 'may be adjusted by slots 20 and screw-bolts days or at late hours I have placed under- 21. A weight 22 serves to keep it in its proper position. This frame is provided with'awhite cloth orwhite pasteboard or other reflecting material, and thus it is adapted to collect the rays and reflect them to the glass plate, which in such a manner is so perfectly lighted that the cloth may be thoroughly examined. The

27 of the belt 28'. To the shaft 23 is keyed a chain-wheel 29, which imparts motion by a chain 30 to a chain-wheel 31 on a shaft 32,

which carries the stuff-receiving roller To prevent contrary revolving of the roller 33, a ratchet and pawl 34B are provided for.

The device and its special arrangement thus described are of great importance for the examination especially of umbrella stuffs, which operation could not before be carried out in such a simple and exact manner as by my device.

What I therefore claim, and desire to secure by Letters Patent, is

A device for examining and correcting umbrella stufi, consisting of two standards having a roller at their top to receive the stuff, a brake arranged to act onsaid roller, a frame below said roller adjustable radially and vertically, a glass plate inclosed by said frame, a reflector arranged below the frame and adjustably mounted, and a second roller adapted to receive the stuff, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KARL EGGEMANN.
